Asymmetric Digital Subscriber Line (ADSL)
|
Asymmetric Digital Subscriber Line (ADSL) is a form of DSL, a data
communications technology that enables faster data transmission over copper
telephone lines than a conventional voiceband modem can provide. It does this
by utilizing frequencies that are not used by a voice telephone call.
A splitter or micro filters allow a single telephone connection to be used for both
ADSL service and voice calls at the same time. Because phone lines vary in
quality and were not originally engineered with ADSL in mind, it can generally
only be used over short distances, typically less than 3mi (5 km).
At the telephone exchange the line generally terminates at a DSLAM where
another frequency splitter separates the voice band signal for the conventional
phone network. Data carried by the ADSL is typically routed over the telephone
company's data network and eventually reaches a conventional Internet network.
